To all whom'zt may concern-.-

' Be it known that we, THoMAs FLANA- GAN and MIeHAm. J FLANAQAN, citizens of the United States', residing at Tulsa, 1n the county of Tulsa and State of Gklahoma, have invented certain new and useful Improvements in 4Burners for Gas and 011,

. of which 'the following is a specification,

-reference bein had therein to the accompanying drawing.

This invention relates to improvements "in burners ofthat type more particularly designed for use `in connection with natural gas and' oil, although useful for either natural as or oilto'be'used alone, as will hereina r appear. 1

In the a o mpanymg drawings we have illustrated he preferred embodiment of the invention, a'ndthe lmproved detailsvof conwill be apparent from the specific descripu tion hereinafter contained when read in con- -1 Vnection with Such of the burner.

struction and arrangement of-parts thereof drawings. In the drawingsl Figure 1 isa lo gi'tudinal sectional view Fig. 2 ,is an elevation of the same; and,

` *Figa 3 is an end view.

. @ferring lmore specifically` to the drawings whereinlikeieference letters designate corresponding parts,l in the several views A represents an outer casing of relatively large size terminating atene endv in the integ'ml reducedl nozzle portion B and at theother end in the ianged bearing C. Near the bearing end of the member A andproject-ing from the top thereof is an'integral valve chamber D provided with avalve seat E bordering a port F communicating with the chamber G on the vinside of the member'A.

H is a valve bonnet threaded into the up-l I' 'l l' per end of theivalve chamber D, the same adjustably sup orting theithreaded stemV J of the valve having the usual operating hand wheel L.' TheV valve chamber I) has .a

series of ports or openingsrfor air, aroundV the` side thereof as shown' at M disposed to* be above the valve KA when on its Seat E, but to alford communication `from the exterior of the device tothe chambers AF and G when the valve is raisedY from its seat to open the same. Inserted in the bearing portion C of the member A and held against. rotation with referencevto'the latter by a flanged end 0 detachably bolted tothe bearing ange as at ,P is a sleeve N reduced in diameter for.

sources 4(not necessary to be' illustrated herein) feeding through the as nipple S or oil nipple S' sleevedthroug the outer casing A and threaded through the sleeve Nto discharge intothe interior of the latter.

U'is a steam pipe arranged within the oill and gas chamber T carried by a knuckle V threaded into the outer end of thesleeve N and communicating with any suitable source of steam supply as through a nipple W, the

enti of theknuckle being normally vclosed through the medium of a detachable plug X' l adapted to afford accessto the interior of the steam pipe for the .purpose of clean-v ing, etc.

he nipple W ma be disposed atany desired anglewith 're erence to the device b merely adjusting the knuckle in a rotary d1- rection enabled by its threaded mounting atv and the squaring of the exterior thereof as at fu for the accommodation of a wrench or similar tool.

The end of the steam pipe'U terminates considerably short of the end ofthe sleeve N, 'or more s' ecilically at a point 'adjacent to the oil an gas nipples S and S', and in thisend of the steam vpipe is removably inserted a suitable apertured plug Y constituting a jet nozzle 4discharging into the chamber T in axial alinement with the oil und gas y tube Q; The outer surface of the steam 1ct nozzle Y fiares toward the end of the same and toward the inner wall of the Sleeve N as at Z to afford an annular reduced passage of the sleeveN. i

In using ,the -device the air valve is adjusted to admit the de'sired pro ortion of air to mingle with the mixture ischarged around the nozzle'Y Within the chamber T` Y into the chamber near the end ofthe nozzle B; they steam through a suitable valve (not shown) is admitted through `the *steam pipe and discharged through the liet nozzle Y into the chambers 'l and Q. whiclrwill create a suction facilitating the "l'ccdingol' the oil or gas or-hoth into the sleeve il,'\\heuce it flows i outwardh Ain a cylindrical film formation the around the enlargingi cud of the steam jet nozzle into the vmixing chamber rl beyond the nozzle and into the tube -Q where the oil, gas and steam effect Vau intimate mixture which. emitted through the contracted end h ol the tubev Q, will the'remixwith the air and tend to suc-lt the airinto and through the device. Where, oil only used. tbegas is cnt ofi at the nipple Sthrough any approved valve mechanism (not shown), and

where gas vonlyT isused'the "supply to the, oil nijnilefS is similarly cut ofi'. Then 1t is desired to enrich the natural gas when in a vwea k or impoverished State, loth oil and gas are admitted `in appropriate' proportions through the nipples S and "S, as will be obvious. l
